Hello,
I have no knowledge about bricks and don’t know which are the best. You can find a lot of information on the internet, but in my opinion, all bricks look quite similar. Which bricks are actually the best for thermal insulation and soundproofing? What thickness should be used? Many also use thinner bricks and then add 5cm (2 inches) of polystyrene or something similar. What experiences have you had?

In my opinion, with a 36.5cm (14.4 inches) block, sound insulation is negligible; however, how do you come to the conclusion that aerated concrete should cause problems with structural stability?
Best regards

Regarding the 36.5cm (14.4 inches) block, it likely provides better sound insulation than thinner options; however, it still performs significantly worse in this aspect compared to other blocks. The main concern here is with thin interior walls, where autoclaved aerated concrete (AAC) blocks are generally not recommended.
As for structural stability, naturally, using 36.5cm (14.4 inches) or 40cm (15.7 inches) AAC blocks for a single-family home usually poses no problems. However, other types of blocks have higher bulk densities, which positively impacts load-bearing walls, especially internal ones, allowing these walls to be constructed much thinner.
The only advantages I see in this type of block are the ease of handling (which is not my area of responsibility) and its thermal insulation performance, which can also be achieved today with insulated pumice or clay blocks, or alternatively with sand-lime bricks plus an external thermal insulation composite system (ETICS).

... have you ever heard that this material comes in different densities? That lightweight construction in the attic is preferred over all masonry types — including calcium silicate blocks?
I am against generalizations as well as one-sided assessments...
Every homeowner decides individually which material they want to use; most reputable builders offer cost-neutral alternatives during the structural shell phase. Poroton undeniably has its advantages but also its equally undeniable disadvantages — the same applies to pumice or calcium silicate blocks. Just considering that an external thermal insulation composite system (ETICS / external wall insulation) has to be installed, meaning it creates an ideal environment for mold growth inside a plastic film ... necessitates ventilation ... and so forth...
If you want to have a fact-based discussion with me, I am happy to do so; however, one-sided viewpoints are, in my opinion, not helpful.
Kind regards

Regarding structural engineering, of course, you won't have any issues with 36.5 or 40 cm (14.5 or 16 inches) aerated concrete in a single-family house, but other masonry materials have higher bulk densities, which positively affect load-bearing walls (especially internal ones) because they can be made significantly thinner...
